摘要：

To prepare FTCF, PET film was dipped in Fe(OTs)(3) n-butanol solution for Fe(OTs)(3) adsorption and suspended in EDOT cyclohexane solution for EDOT depositional polymerization. The adsorbed Fe(OTs)(3) were determined with idometry and the synthesized PEDOT coating were characterised with FTIR and UV-vis spectroscopes. The sheet resistance and transmittance of synthesized PEDOT/PET films were measured with four-point probe and spectrophotometer. The effect of Fe(OTs)(3) drying time and polymerization time on sheet resistance and transmittance were investigated. From 80 mmol/L of Fe (OTs)(3) solution, PET film could adsorb Fe(OTs)(3) at a magnitude of 1.7 mmol/m(2). As PET with adsorbed Fe (OTs)(3) was suspended in EDOT solution, EDOT monomers deposited to PET surface and joined one another to form positive charged PEDOT molecules continually, resulting in transparent and conductive PEDOT coating on PET film. After dipped in 80 mmol/L Fe(OTs)(3) solution, dried at temperature 40 degrees C and suspended in 80 mmol/L EDOT solution for 15 h, PEDOT coating with thickness about 100 nm and conductivity 530 S/cm generated; flexible PEDOT/PET films with transmittance above 80% and sheet resistance below 200 Omega/area were produced.
